Update on this: We’ve tweaked our email setup a little bit, and I can no longer directly re-subscribe people. We do want to build our own unsubscribe system that will let people re-subscribe after an accidental unsubscribe. For now, the best approach is to change the email address on your account. For instance, if you used example@gmail.com, you can change it to example+1@gmai.com. Then you’ll start getting email again.
If you’re using Certbot, you can run:
certbot register --update-registration
Thanks,
Jacob
